ASCII Table

Demonstrates advanced Arduino serial output functions.

Last revision 01/25/2022

This example demonstrates the advanced serial printing functions by generating on the serial monitor of the Arduino Software (IDE) a table of characters and their ASCII values in decimal, hexadecimal, octal, and binary. For more on ASCII, see asciitable.com and http://en.wikipedia.org/wiki/ASCII

Hardware Required

  • Arduino Board

Circuit

circuit

None, but the board has to be connected to the computer through the serial port or the USB port.

Code

The sketch waits for a serial connection in the 

setup()
then prints line by line the ASCII table up to the last printable character. When this is accomplished, it enters an endless loop in a while structure and nothing else happens. Closing and opening the serial monitor window of the Arduino Software (IDE) should reset the board and restart the sketch.
